since this is a custom design, you could modify the keyslots as to not be a problem. Helmet looks great,so far. As to the sword, make the crosspieces in two halves with enough room at the top of the skull for the tang of the blade to go into the handle. If the tang doesn't, your sword will fall apart and have major balance problems. I know a little about swords, and could draw this for you if you're not quite sure what I am saying. Keep it up, my trashcan turned out not so well, but others have been great.
